ABSTRACT:
Methods for modeling and executing systems in a linearly-implicit formulation of ordinary differential equations (ODEs) or differential algebraic equations (DAEs) are provided in modeling environments. The modeling environments may include block diagram modeling environments, such as time-based block diagram modeling environments. The block diagram modeling environments may include or be coupled to other modeling environments, such as physical modeling environments, so that models created in other modeling environments may also be introduced and solved in the linearly-implicit formulation of ODEs or DAEs in the block diagram modeling environments. Models describing the systems in the linearly-implicit formulation of ODEs or DAEs may also be created directly by users using user-defined blocks in the block diagram modeling environments. The present invention provides solvers for solving the system described in the linearly-implicit formulation of DAEs as well as ODEs in the block diagram modeling environment.
